我刚接触编码,只是学习Python.我搜索了答案但找不到答案.
我正在尝试制作一个用于学习目的的计算器,但我无法进行底部keyboard frame扩展,或者buttons内部扩展以匹配根窗口的边界
这是我的代码:
from tkinter import *
# main window configuration
root=Tk()
root.geometry("1000x1000")
root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=1)
# main window frames
topmenu=Frame(root,padx=5,pady=5)
display=Frame(root,padx=5,pady=5)
keyboard=Frame(root,padx=5,pady=5,bg="red")
topmenu.grid(row=0,column=0)
display.grid(row=1,column=0)
keyboard.grid(row=2,column=0)
# topmenu widgets
# display widgets
#keyboard widgets
# prima riga
percentagebutton=Button(keyboard,padx=5,pady=5,text="%")
squarerootbutton=Button(keyboard,padx=5,pady=5,text="?x")
squarebutton=Button(keyboard,padx=5,pady=5,text="x²")
inversebutton=Button(keyboard,padx=5,pady=5,text="1/x")
percentagebutton.grid(row=0,column=0,sticky='EWNS')
squarerootbutton.grid(row=0,column=1,sticky='EWNS')
squarebutton.grid(row=0,column=2,sticky='EWNS')
inversebutton.grid(row=0,column=3,sticky='EWNS')
# seconda riga
resetbutton=Button(keyboard,padx=5,pady=5,text="C")
deletebutton=Button(keyboard,padx=5,pady=5,text="?")
divisionbutton=Button(keyboard,padx=5,pady=5,text="÷")
resetbutton.grid(row=1,column=0,columnspan=2,sticky='EWNS')
deletebutton.grid(row=1,column=2,sticky='EWNS')
divisionbutton.grid(row=1,column=3,sticky='EWNS')
# terza riga
sevenbutton=Button(keyboard,padx=5,pady=5,text="7")
eightbutton=Button(keyboard,padx=5,pady=5,text="8")
ninebutton=Button(keyboard,padx=5,pady=5,text="9")
moltiplicationbutton=Button(keyboard,padx=5,pady=5,text="X")
sevenbutton.grid(row=2,column=0,sticky='EWNS')
eightbutton.grid(row=2,column=1,sticky='EWNS')
ninebutton.grid(row=2,column=2,sticky='EWNS')
moltiplicationbutton.grid(row=2,column=3,sticky='EWNS')
# quarta riga
fourbutton=Button(keyboard,padx=5,pady=5,text="4")
fivebutton=Button(keyboard,padx=5,pady=5,text="5")
sixbutton=Button(keyboard,padx=5,pady=5,text="6")
minusbutton=Button(keyboard,padx=5,pady=5,text="-")
fourbutton.grid(row=3,column=0,sticky='EWNS')
fivebutton.grid(row=3,column=1,sticky='EWNS') …
